can you help me on this subject. thank you

Hi,

did you try passing options directly from the command line instead of using a conf file ?
what does your ntop.conf looks like ?

thank you for do your answer.
I see that you live in Strasbourg can you continue in French?

if not it is always similar for the order with the options derriere.
my file of conf resembles that:
### You should copy this file to it's normal location, /etc/etc/ntop.conf
### and edit it to fit your needs.
###
### ntop is easily launched with options by referencing this file from
### a command line like this:
###
### ntop @/etc/ntop.conf
###
### Remember, options may also be listed directly on the command line, both
### before and after the @/etc/ntop.conf.
###
### For switches that provide values, e.g. -i, the last one matters.
### For switches just say 'do things', e..g -M, if it's ANYWHERE in the
### commands, it will be set. There's no unset option.
###
### You can use this to your advantage, for example:
### ntop @/etc/ntop.conf -i none
### Overrides the -i in the file.

### Sets the user that ntop runs as.
### NOTE: This should not be root unless you really understand the security risks.
--user root

### Sets the directory that ntop runs from.
--db-file-path /var/ntop

### Interface(s) that ntop will capture on (default: eth0)
--interface eth0,eth1,eth2

### Configures ntop not to trust MAC addrs. This is used when port mirroring or SPAN
#--no-mac

### Logging messages to syslog (instead of the console):
### NOTE: To log to a specific facility, use --use-syslog=local3
### NOTE: The = is REQUIRED and no spaces are permitted.
--use-syslog=local3

### Tells ntop to track only local hosts as specified by the --local-subnets option
#--track-local-hosts

### Sets the port that the HTTP webserver listens on
### NOTE: --http-server 3000 is the default
--http-server 3000

### Sets the port that the optional HTTPS webserver listens on
#--https-server 3001

### Sets the networks that ntop should consider as local.
### NOTE: Uses dotted decimal and CIDR notation. Example: 192.168.0.0/24
### The addresses of the interfaces are always local and don't need to be specified.
--local-subnets xxx.xxx.xxx.xxx/24

### Sets the domain. ntop should be able to determine this automatically.
--domain mondomaine.com

### Sets program to run as a daemon
### NOTE: For more than casual use, you probably want this.
#--daemon

Hi,

I could continue in french, however I'm sure that other LQ users won't even have a look at your problem if we don't post in english...
[as a matter of fact I just moved to ireland last monday, so thanks, i had forgotten to edit my profile]

you use much more options than i ever used with ntop... maybe you should begin with as little options as possible (--interface eth0 --http-server 3000).

i see one anormal thing: the subnet config (xxxx.xxx.xxx.xxx/24 is no subnet ! you should comment this line).

Ok no problem

I have remakes a test by putting in comment all the lines except --user root, --dB-file-path/var/ntop, --interface eth0, --domain mondomaine.com and --HTTP-server 3000 but I have the same error message.
in/var/log/messages I have that:
Aug 1 14:12:02 fw-agence1 ntop[5886]: ntop v.3.1 (Dag Apt RPM Repository) MT (SSL)
Aug 1 14:12:02 fw-agence1 ntop[5886]: Configured on Jul 26 2005 7:39:51, built on Jul 26 2005 07:41:59.

Aug 1 14:12:02 fw-agence1 ntop[5886]: Initializing ntop

no error messages

I am also running FC4 and ntop 3.1. I am getting the same errors as the above poster.
The config file that I am using has just the minimum required.

Can anyone help us?

Any ideas?
Should I ditch the idea of running ntop on FC4 and try it on FC3?

Any help would be greatly appreciated.

Thanks

Same problem here.
I had ntop running on Feddore core 1.
When I reinstalled Fedora core 4 and installed ntop,
and do "/etc/init.d/ntop start" I get:

007b2000-007b3000 rwxp 0001d000 03:02 505620 /usr/lib/libjAborted

===========================================================
I get the above error with a /etc/ntop.conf as below (all comments deleted) and with a config file with everything commented out.

--user ntop
--db-file-path /var/ntop
--interface eth0
--local-subnets 169.254.1.0/24


/var/ntop has owner root owner and group ntop.
Contents of /var/ntop have ntop owner and group root.

Any help would be most appreciated. Thanks

Hi all,

I had the same problem. I found success using the latest ntop from CVS. Download that, compile and install and you should be right.

head over to the thread running in the ntop-devel mailing list for more info:

Happy Ntoping,
